5.4 Mounting Drives 5.4.1 Check before mounting Reconfirm if the setting terminals are set correctly according to Table 5.8 before mounting the MP model drive in the system cabinet. For setting terminals location, see Section 5.3. The MC model drive does not require the following check.

The general mounting method and items to be checked are shown below. See Subsection 4.1 for the details of requirements for installing the IDD. 1) With a system to which an external operator panel is mounted, if it is difficult to access the connector after the drive is mounted on the system cabinet, connect the external operator panel cable before mounting the drive. 2) Fix the drive in the system cabinet with four mounting screws as follows: • The drive has 10 mounting holes (both sides: 3 × 2, bottom: 4). Fix the drive by using four mounting holes of both sides or the bottom. (See Figure 4.5) • Use mounting screws whose lengths inside the drive mounting frame are 6.35 mm or less when the screws are tightened (see Figure 4.4). • When mounting the drive, be careful not to damage parts on the PCAs. 3) Check to ensure that the DE is not touching the frame on the system side after tightening the screws. At least 2.5mm of clearance is required between the DE and the frame. (Indicated in Figure 4.4) 5 - 10 C141-E128-01EN
